I recently installed OpenBSD on my xiaomi notebook air 12, I managed to launch Xorg using efifb, but now the touchpad doesn't work. I'm new to this OS, so I don't know how to troubleshoot this.
I joined a dmesg;sysctl hw.sensors file, can you tell me what I should do now?

I do not see a device in the dmesg that might be a trackpad. This means that the hardware isn't responding to the kernel's probe. Perhaps the device is disabled in BIOS/EFI. More likely, this Skylake computer is just too "new" a system for OpenBSD.

You are running 6.0-release, which was built in July of 2016. You could try a -current snapshot instead of -release, but as noted above much of the hardware is still unknown to the OS.

Also enter BIOS, and see if there are any config for touch pad. If I had my Acer Cloud book set to Advance touch pad in bios it did not work in OpenBSD. If I changed to normal touch pad it worked .. I newer managed to get both mouse button to work from pure touch pad with out hardware button. I find it easier to use OpenBSD on laptop with hardware button for right and left mouse

Thanks everyone for your replies!
I linked the results. I found no trace of a touchpad, maybe it is an i2c one? There is an i2c controller, is there a way to list all attached peripherals, like with lspci?

Edit: I also searched in the uefi, there is no option to configure the touchpad...
